Until now, nearly every smartphone was using lithium-ion batteries. High-end models like the Apple iPhone 16 Pro still rely on this type of battery. On the other hand, Chinese brands like Huawei, Honor, and Xiaomi are shifting towards silicon-carbon batteries. These companies promote this new technology as being safer, greener, and having a longer lifespan.
Potential for Greener Solutions
There’s still room for making this technology more eco-friendly since silicon isn’t currently recycled on a large scale. Nevertheless, it does offer a significant advantage to smartphone users: increased energy density. This feature allows the Honor X9c to include a 6,600 mAh battery in a lightweight design of just 189 g (0.42 lb). Additionally, the new Realme Neo7 comes with an even larger 7,000 mAh battery. This innovation has helped the Honor X9c achieve the highest ranking in battery performance according to DxOMark, which isn't surprising given its remarkable battery endurance.
Impressive Battery Life
With just one charge, the Honor X9c provides over 42 hours of talk time, 29 hours of video playback, and 15 hours of gaming. Even under “moderate” usage, the X9c can last up to four days. DxOMark reports that this mid-range device can endure for over two days, even with daily usage of seven hours.
Charging is pretty efficient too, as the phone supports 66 watts via USB-C, allowing it to fully charge in just a little over an hour, and it can reach 80% in about 42 minutes. While this isn’t groundbreaking, it is still quite impressive given the large battery size. For context, the Apple iPhone 15 Pro Max takes more than two hours to fully charge its smaller 4,441 mAh battery.
Conclusion
Overall, the shift to silicon-carbon batteries from these manufacturers could change the landscape of smartphone technology, offering users longer-lasting devices while also addressing some environmental concerns, even if improvements are still needed in recycling practices.
